Answer:
Whether it's large enough or not depends on what you need to do with it.
If you plan to use it to ship water for the population of Las Vegas from Hoover Dam,
then no, it's not large enough to do the job.
If you're going to use it to sip cold sweet tea from the bottom of a tall frosty glass,
then it's much larger than it needs to be for that job.
It all depends on the intended application.
